25-Hydroxy Vitamin D3

High levels of the 25-Hydroxy Vitamin D3 biomarker could indicate that your body is absorbing too much Vitamin D. This could be due to consuming large amounts of Vitamin D through your diet or supplements, or it could be a sign that your body is not properly regulating Vitamin D. Certain medical conditions, such as sarcoidosis, can cause your body to make too much Vitamin D. Some medications, like antifungal drugs or antiretrovirals used for HIV, can also increase your Vitamin D levels. High levels of Vitamin D can lead to a condition called hypercalcemia, where there's too much calcium in your blood, which can affect various parts of your body, including your bones, nerves, kidneys, and heart.

Symptoms of high levels of 25-Hydroxy Vitamin D3 could include nausea, vomiting, weakness, frequent urination, and kidney problems. In severe cases, it can cause bone pain and heart arrhythmias.

Low levels of the 25-Hydroxy Vitamin D3 biomarker could suggest that you're not getting enough Vitamin D from sunlight or your diet. Sunlight is a key source of Vitamin D for our bodies, so if you're spending a lot of time indoors or live in a place with little sunlight, your levels might be low. Similarly, if your diet lacks Vitamin D-rich foods like fatty fish, cheese, and egg yolks, you might not be getting enough. Certain medications, like anticonvulsants, glucocorticoids, antifungals, and medications for HIV/AIDS, can also interfere with how your body absorbs or processes Vitamin D, leading to lower levels. Additionally, conditions that affect fat absorption, such as celiac disease, Crohn's disease, and liver or kidney diseases, could result in lower Vitamin D levels because Vitamin D is a fat-soluble vitamin.

Symptoms of low levels of 25-Hydroxy Vitamin D3 could include fatigue, bone pain, muscle weakness, mood changes, and frequent illness or infections.
